I did installed version 30. But what I don't like in it is that Opera keeps starting a lot of instance in my system. When I boot up Opera 30 (30.0.1835.59, stable update stream), it starts about 5 to 10 instances. One more thing is that in the Opera 30, the PPAPI version is 17,0,0,188. Meanwhile in Chromium it's 18,0,0,160.
